:DOUBLE-.CIRCUIT PUSH-BUTTON SWITCH.

Application led November 11, 1919.

To (1U lwle-0m. fait may concern.'

lie it known that L Dino l), RAoiiNovioH, a subject ot' the' Kingdom ot' Serbia., residing at San Francisco, in the count)v of San Francisco. State ot' California, have invented a new and useful Double-Circuit Puslnlutton Switcln ot which the following is a specification. in such t'ull and clear terms as will enable those skilled in the art to construct and use the saine.

This invention rclatesto a push button switch which is capable of closing a contact or several contact-s in one movement. and ot' breaking the contacts in another movement in the saine direction, a spi'iiig restoring the push button to its normal position.

Another object of the invention is to provide a switch capable oi connecting several circuits should that be desired.

Other objects ot' the invention will appear as the description proceeds.

An embodiment oi the invention is shown in the accompanying drawings in which the same reference numeral is applied to the saine rc't'crencc throughout7 but l am aware that there may be modifications thereof...v`

Fig. l is a vertical sectional view ot the switch, v

Fig, 2 is a front view of the switch,

Fig. 3 is a sectional view on line 3-3, Fig. l, and

Fig. 4 is a sectional view on line 4-4, Fig. l. f

The numeral l indicates the t'ace plate of the switch to which the tube 2 is co1inected, the latter tube having the contact springs 3 to @connected thereto in pairs. Inside the tube 2 is a slidable tube i' held from the rotation by the short screw S and provided with the slots 9 to 14 inclusive through two of which the contact springs project.

Slidahle within the tube 7 is the roda-l5 which is provided with an indicating arrow 1G at one end and with a. plate 17 at the other end to engage the tube 7. A spring 18 holds the switch normally in the position shown in Fig, l and a plug 19 holds the spring in place. A

The, rod .l5 has two contact springs 20, 2l positioned diainctrical'liv opposite and a` spring latch 22 at one endl while b etwecn the two springs 2 2l there is a spring 23 the object of which is to connect either ol the contacts 3, 4 or 5, 6 inpairs or the springs 20, 21 may be connected to both pairs of Serial No. 337,207'.

contacts at one time. The operation of this switch is as follows:

r he normal position of the switch is illus trated in Figce l, and corresponds to the position 'of allot' the electric circuits being open. lt' it `is desired to ring the bell and supply the lights with current atthe same time` the button l5 is pushed in until the Spring 2() and spring 21 press up throng-h the respective slots inthe sleeve 7 until said I springs contact with the plates 3 and 4, and

5 and 6 respectively. These two springs are stiff enough tor hold the pushcbutton in the position indicated. When it is desired to put out the lights pushed in still `further. This will cause the .lug 26 to engage the latch 24 and release the sleeve 7, and the latch 22 will then carry the 'cleeve 7 back so that the contacts 3 and 4, and 5 and 6 cannot further .connect with the springs 20, 2l, and unless pressure is relased from the pushy button, the spring 18 will restore. the sleeveand push button to the position shown in Figure l.

lt' it is desired to connect.r the contacts 3 vand 4 only, they push button will be turned so that'the snap 22 .will engage 9() degrees the slot 13 instead ot.' the slot 14. This will bring the spring 23 into a position to be engaged it the push button is pushed inwardly with the contact plates 3 and 4. and said spring is suiiciently stiff to hold the push button in that position when the spring'23 presses up into the slot in which the plates 3 and .JC project. v

As was previously described if it is desired to put out the lights pressure is applied to the push button and thereupon .the sleeve 7 is pushed backwardly so that the plates 3 and l cannot further contact with the spring 23. As soon as pressure is released the spring 18 will push the push button and sleeve to the position shown in Figure l, the inertia being suicient to jump the spring 23 out of theslot in which Ait may be engaged.

the push button 15 is` If the circuit connected with the plates 5 i on will, push the sleeve `(in toilowing its will bring thelatch 22 release bythe lug' 27 contacting With the 'latch 24, and uponremoving the pressure fromthe push button, the push but-ton and sleeve Willnbe restored to the positions shown in Figure 1 by the spring'A 18.

A hook 24 locks the tube 7 in the position shown in Fig. l until one of the lugs 25, 26 or 27 engages and releases it and permits'it to slide back to break the contacts.`

As shown, when the rod l5 is pushed in, the lights and the bell circuit will both be closed and the springs 20, 21 will snap `up into the slots in the tube 7 with suliicient force to hold the rod l5 in the given posh tion until it is pushed further in and thenit will then be returned by the spring 18 along with the tube 7. t

llVhen the rod 15 is turned so its indicating arrow corresponds to lights or bell those contacts will be made singly.

WVhat I claim is as follows, but various modifications may be made in the construc-v button to its normal position.

2. push button switch comprising a tube carrying contact plates, a second. tube. slidable within the first tube and having slots into which. said Contact plates may project, a push button slidable in the second tube, means carried by the push button to connect said contact plates, a spring' to restore the push button to its .normal position, and means to permit the push button to be rotated to connect different .pairs of contacts.

` 3. A push button switch comprising a slide, Contactv plates carried thereby, a. tube movable in said slide and having slots into which said contacts may project7 a push button slidable in the tube, a latch for holding the tube in a fixed position.y ineansv to release the latch when the contacts are to be broken whereby the tube is carried along' with the push button, and a springfor re storing' the push button and tube to their initial positions after the contacts have been disengaged.

4f.. A push button switch comprisinpr a slide having opposite pairs of Contact plates, a slotted tube movable in said slide, a push but-t0n slidab-le in said tube, nieans to hold the push button in a position to connect either or both pairs oic contacts. means to hold the tube in a fixed position. means on the push button to release the tube when the contacts are disengaged. and a springr for restoring the push button and slotted tube to their initial positions when thecontacts disengaged.
